5514.21.00.90 - Plain weave duck (219)

This HTS category, 5514.21.00.90, specifically classifies "plain weave duck" fabrics. These are woven fabrics made from synthetic staple fibers, predominantly polyester in this sub-category, containing less than 85% by weight of these fibers and mixed mainly or solely with cotton. The fabric must exceed 170 grams per square meter in weight and be dyed. The term "duck" generally refers to a strong, plain-weave fabric, often with a coarser weave than poplin or broadcloth, historically used for durable applications.

This category is distinguished from its sibling, 5514.21.00.20 (Poplin or broadcloth), by its weave construction and often coarser texture. While both are dyed plain-weave fabrics of synthetic staple fibers and cotton, "duck" typically implies a more robust weave suitable for heavier-duty purposes, whereas poplin and broadcloth are known for their finer, smoother finishes. The specific designation "duck" as opposed to other plain weave constructions is the key differentiator.

As this node is a leaf node, there are no further subcategories to introduce. Classification within this specific HTS code relies on the precise identification of the fabric as "duck" and adherence to the criteria of synthetic staple fiber content, cotton mixture, weight exceeding 170 g/m², dyed state, and plain weave construction. Importers and exporters should carefully verify these characteristics against their product specifications to ensure accurate classification.
